IMPROVEMENT IN SOLDERlNG-IRONS.l

Specification forming part of Letters Patent No. 29,039, dated July 3, 1860.

To all wh-om, it may concern.-

Be it known that I, LESTER IPArnE, ofthe city and county of Peoria-fand State of Illinois, have -invented a new and useful Im provement in Soldering-Irons; and I do hereby declare the following to bea full and exact description of the same, reference being had to the accompanying drawin/gs,1and to the letters of reference marked thereon, in which- Figure 1 is aperspective View;` Fig. 2 represents the outer covering or shoen B, with ring H connected to the shoe BV by spiral springs ,G and wire JJ. Fig-ure 3 shows' heater7'A and handle C, with its groove El and recess I), made to yreceive the wire J and H, as shown in Fig. 1. Fig-.3 alsoshows the iron rod S that connects the heater A to the handle C.

The nature of my invention consists in the employment of a castor wrought iron heater, A, (see Fig. 3,) provided with a coveringorv shoe, B, (see Fig. 2,). made of sheet-copper, and securing the saine Vto the heater A by a spring, (marked G,) and wires J J, or any other arrangement that will keep a constant tension on the `shoe B and exert apforee sufficient to keep the shoe from becoming loose on the heater A while the heater is cooling and contracting and the shoe is heating and expanding. I 'make a groove in the handle C (see Fig. 3) to receive the wire J and prevent its being in the Way ofthe hand when the'ironis in use. At the end of the wooden handle C, I inake'a recess, I), (see Fig. 3,) to receive the ring II and hold it in position While the solderingiron is being used.

In order to heat my soldering-iron, I defor use, it may readily be attached to the shoe by inserting the point of the heater into the shoe and pulling the ring H, so as to stretch4v out the spiral spring long enough to allowthe ring H to enter the-recess l?. This secures' the shoe to the heater, and the force exert-ed on lhe shoe by the spiral spring effectually prevents the shoe .from becoming loose as the heater contracts by cooling. I `usually e1nployv two or more heaters at a time, all being made to t the same shoe, while one shoe only will be required for each person to work with,

I substitute'a very cheap met-al (cast or wroughtiron) for copper, and thereby reduce the expense of making soldering-irons tive hundred per cent., and the almost indestructible nature of the material of which'the heater is composed renders it capable of being heated by stone-coal without injury, thus' rendering it useful in every family for repairing tinware, &c.

I do away with all liability of destroying the part of the iron that is tinned, as I do not expose the copper shoe to the heat of the re.- 'lhework and delay of cleaning the soot and ashes from the point of the soldering-iron every time it is taken from the fire is "entirely avoided, aud this iron can be used at a much higher temperature than can be applied tothe ordinary soldering-iron without danger of destroying the face ortinned part of theiron. Consequently smoother soldering can be done with it, and much more work can be done at LESTER RATEE.
